论文标题Microstructure evolution and mechanical properties of a nickel-basedhoneycomb sandwich aged at 900 ？C

作者Zhang Qiuming, He Xiaodong, Li Yao

期刊名称Materials Science and Engineering A

期卷530

简单介绍A nickel-based superalloy honeycomb sandwich was manufactured by high-temperature brazing. Themicrostructure evolution and the out-of-plate mechanical properties were determined for honeycombsandwiches aged at 900 ？C. The maximum tensile stress was 28.5MPa and the compressive yield strengthwas 29.6MPa for the original specimens. These parameters decreased to 22.2MPa and 18.8MPa for specimensaged for 10 h, to 19.3MPa and15.5MPa for specimens aged for 20 h and to 20.3MPa and 16.5MPafor specimens aged for 30 h, respectively. There was not obvious yield process in all curves of tensile stressversus strain. With increasing aging time, the tensile elongation decreased, and the intermetallic compoundsand the eutectic structure in the brazing region disappeared, and the solid solution approachingthe matrix gradually increased.

简单介绍A nickel-based superalloy honeycomb sandwich was manufactured by high-temperaturebrazing. The microstructural evolution and the out-of-plate mechanical properties weredetermined for honeycomb sandwiches aged at 800 °C. The maximum tensile strength was28.5 MPa and the compressive yield strength was 29.6 MPa for the original specimens. Theseparameters decreased to 24.7 MPa and 23.5 MPa for specimens aged for 10 h, to 24.9 MPa and21.5 MPa for specimens aged for 20 h and to 26 MPa and 24.8 MPa for specimens aged for 30 h,respectively. With increased aging time the tensile elongation decreased, the intermetalliccompounds and the eutectic structure in the brazing region disappeared, and the solidsolution approaching the matrix gradually increased.
